In order to promote the understanding to the principle of the invention, with reference to the embodiment shown in accompanying drawing and described in following explanation.Therefore be understandable that, the scope be not meant to limit the present invention.Be understandable that further the present invention includes and any changes and improvements of described embodiment and comprising are applied further concerning the principle of the invention the those skilled in the art affiliated by the present invention.
Securing member percussion device 100 shown in Fig. 1 comprises shell 102 and securing member chuck (cartrige) 104.Shell 102 defines handle portion 106, battery receptacle 108 and drive part 110.Securing member chuck 104 in embodiment is biased by the spring, the securing member of such as nail or brad and so on to be pushed continuously one by one the " loaded " position of contiguous drive part 110.With reference to figure 2, a part for its housing 102 is removed, and shell 102 is arranged on two-piece type (two piece) framework 112 of support dc motor 114.More clearly as shown in Figure 3, two springs 116 and 118 lay respectively at guider 120 and 122 around.Solenoid (solenoid) 124 is positioned under guider 120 and 122.
As shown in Figure 4, the motor 114 of framework 112 is fixedly attached to by bearing 128 support lever arm component 126 rotationally.In addition with reference to figure 5 and 6, lever arm unit 126 comprises the flywheel 130 and flywheel driving wheel 132 that are supported rotationally by axle 134.Multiple groove 136 is formed in the periphery of flywheel 130.Extend between flywheel driving wheel 132 and the driving wheel 140 being connected to motor 114 output shaft 142 with 138.Lever arm unit 126 comprises the spring well 144 and 146 that two are held spring 148 and 150 respectively.Find out better from Fig. 4, pin holds recess 152 and is positioned on the lower surface of tongue piece (tongue) 154.
Continue with reference to figure 3 and Fig. 4, the idle running position of (free-wheeling) roller 156 above actuator 160 is installed to framework 112 by bearing 158 rigidity.Actuator 160 is included in the anvil (anvil) 162 of one end and the guide post flange 164 in contrary one end.Permanent magnet 166 is also positioned on actuator 160.Actuator 160 can move at bolster 168 before guider 120 and 122 front end with between a pair rear bolster 170 and 172 at the opposite ends place of guider 120 and 122.Front bolster 168 defines centre bore 174, and it leads to the driving passage 176 in securing member chuck 104.Hall effect sensor 178 is positioned at the front of idle rollers 156.
With reference to figure 2, actuating mechanism 180 comprises slide bar 182, and its one end is connected to work (workpiece) contact (WCE) 184, is connected to pivotal arm 186 in contrary one end.Spring 188 by slide bar 182 towards WCE 184 bias voltage.Pivotal arm 186 pivotally 190 pivotables and comprise hook portion 192, as shown in Figure 7.This hook portion 192 is configured to be engaged in the locking groove 194 of trigger 196.Trigger 196 pivotally 198 pivotables and aim to start spring-biased switch 200.
As shown in Figure 8, spring-biased switch 200 is used for providing input to control circuit 210.Control circuit 210 comprises the processor 212 controlling motor 114 and solenoid 124 operation.The energy of circuit 210 provides with the same battery 214 by being connected to battery receptacle 108 (as shown in Figure 1) of energy of motor 114 and solenoid 124.The signal that processor 212 receives from spring-biased switch 200, hall effect sensor 178 and flywheel speed sensor 220 inputs.Control circuit 210 comprises the timer 2 22 providing input to processor 212 further.Memory 224 is controlled by instruction repertorie, and when being performed by processor 212, this instruction provides the performance of various controlling functions described here.In one embodiment, processor 212 and memory 224 are loaded on microcontroller.
The more details of securing member percussion device 100 and operation initial reference accompanying drawing 1-8 describe.When battery 214 inserts in battery receptacle 108, energy is applied to control circuit 210.Next, operation contact 184 presses near workpiece by operator, and push the work forward in arrow 234 direction as shown in Figure 2 contact 184.The movement of operation contact 184 makes slide bar 182 extrusion spring 188 of actuating mechanism 180 and rotates pivotal arm 186 around pivotal pin 190.With reference to figure 9 and 10, when pivotal arm 186 rotates in arrow 236 direction around pivotal pin 190, the hook portion 192 of pivotal arm 186 turns to outside locking groove 194 along the direction of arrow 236.This permission trigger 196 turns to position as shown in Figure 10 in arrow 238 direction.In Fig. 10, trigger 196 is compressed against on spring-biased switch 200.
When trigger 196 is pressed against spring-biased switch 200, produces signal and send processor 212 to.In response to signal, processor 212 makes the energy from battery 214 be supplied to motor 114, and the output shaft 142 of motor 114 is rotated along the direction of arrow in Fig. 5 230.Therefore, the driving wheel 140 being fixedly attached to output shaft 142 also rotates along the direction of arrow 230.This rotational energy is transferred to flywheel driving wheel 132 by band 138.The rotation of flywheel driving wheel 132 causes axle 134 and flywheel 130 to rotate in the direction of arrow 232.
Flywheel 130 to rotate through flywheel speed sensor 220 sensed, the index signal of flywheel 130 velocity of rotation is sent to processor 212.This processor 212 controls motor 114 to increase the velocity of rotation of flywheel 130, until from the kinetic energy having stored q.s in the Signal aspects flywheel 130 of flywheel speed sensor 220.
In response to the kinetic energy obtaining q.s, processor 212 makes to the energy supply discontinuity of motor 114, allows motor 114 freely to be rotated by the energy be stored in rotary flywheel 130.Processor 212 starts timer 2 22 further and controls solenoid 124 to the state being powered (powered), and pin 264 arrow 266 direction shown in Fig. 4 is outwards actuated by from solenoid 124 thus, and holds recess 152 against pin.Therefore pin 264 forces spring 148 and 150 to be pressed in spring well (well) 144 and 146.When spring 148 and 150 is extruded by the promotion (expulsion) of pin 264, because lever arm 126 is pivotally connected to framework 112 by motor 114 and bearing 128, lever arm 126 rotates around the direction of motor 114 along arrow 266 shown in Fig. 6.
As shown in figure 11, the rotation of lever arm 126 forces the groove 136 of flywheel 130 to enter in the complementary groove 268 of actuator 160.Therefore, actuator 160 clamps between free pulley roller 156 and flywheel 130.This flywheel 130 transmits energy to actuator 160 and flange 164, and it is configured to adjacent springs 116 and 118, is pressed against spring 116 and 118, overcomes the biased of spring 116 and 118 and pushes actuator 160 to front bolster 168.Although the embodiment of Figure 11 includes spring, other embodiments can comprise other elastic components replaced or except spring 116 and 118.These elastic components can comprise extension spring or elastomeric material, such as elastic string or rubber belt.
The centre bore 174 of anvil 162 through front bolster 168 moves in driving passage 176, so that the securing member that the contiguous drive part 110 of shock is arranged along driving the movement in path by actuator 160.
Actuator 160 continuous moving is until whole stroke completes or until timer 2 22 stops.Especially, as shown in figure 12, when whole stroke completes, the contiguous hall effect sensor 178 of permanent magnet 166.Therefore sensor 178 senses the existence of magnet 166 and produces the signal received by processor 212.In response to first in the termination of the signal or timer 2 22 that carry out sensor 178, processor 212 follow procedure interrupts powering to solenoid 124.
In an alternative embodiment, hall effect sensor can be replaced by different sensors.As an example, optical pickocff, induction (inductive)/can be used to provide actuator 160 to reach the signal of whole stroke to processor 212 close to (proximity) sensor, limit switch sensor or pressure sensor.Based on various consideration, the position of sensor can change.Such as, pressure switch can be included in front bolster 168.Similarly, the parts of sensed actuator 160, such as magnet 166, can be positioned at positions different on actuator.In addition, sensor can be configured to different the parts such as flange 164 or anvil 162 of awareness driven part 160.
Cause spring 148 and 150 to expand thus when the direction pivot lever arm 126 contrary with arrow 266 direction (as shown in Figure 6) when being stored in the energy in spring 148 and 150, the power-off of solenoid 124 allows pin 264 to be moved back in solenoid 124.Therefore flywheel 130 leaves from actuator 160.When the movement of actuator 160 is no longer subject to affecting of flywheel 130, spring 116 and 118 causes actuator 160 to move along the direction towards rear bolster 170 and 172 near the bias voltage that flange 164 provides.The movement backward of actuator 160 is buffered part 170 and 172 and stops.
Therefore solenoid 124 and lever arm 126 turn back to state as shown in Figure 4.Therefore, before motor 114 is energized to start another shock sequence again, the signal from trigger switch 200 must be interrupted by release trigger 196.
After securing member is knocked and is released with trigger 196, securing member percussion device 100 leaves from workpiece, spring 188 promotes actuating mechanism 180 and returns to position as shown in Figure 2.In this position, the hook portion 192 of pivotal arm 186 is positioned at the locking groove 194 of trigger 196, as shown in Figure 7.In the structure of Fig. 7, hook portion 192 stops trigger 196 to rotate along the direction of the arrow 238 of Fig. 9.Therefore, first WCE184 is being pressed to workpiece with before allowing to operate in the above described manner, securing member can not be knocked.
In an alternative embodiment, processor 212 can receive the triggering relevant to trigger 196 and to input and relevant WCE inputs with WCE184.The combination that triggering input and WCE input by switch, sensor or switch and sensor provides.In one embodiment, WCE184 no longer needs the actuating mechanism 180 by comprising pivotal arm 186 and hook portion 192 to interact with trigger 196.On the contrary, WCE184 and transmission signal interact to the switch (not shown) of processor 212, and when WCE184's this signal designation is depressed.WCE184 also can be configured to perceived instead of engage with switch.This sensor (not shown) can be optical pickocff, induction/proximity sensor, limit switch sensor or pressure sensor.
In this embodiment, trigger switch can comprise the sensor of detection toggle position, sensor 216 as shown in fig. 13 that.When trigger 196 is reset (reposition), the spring 250 in spring-biased switch 200 be extruded and bar 252 from spring-biased switch 200 outwards movement.This trigger sensor 216 is arranged as the movement of feeler 252.
In this embodiment, trigger sensor 216 comprises light source 256 and optical sensor 258.Light source 256 and optical sensor 258 are arranged like this, and when bar 252 is in position shown in Figure 13, the afterbody 260 (see Figure 14) of bar 252 stops that the light from light source 256 arrives optical sensor 258.But when bar 252 moves to right from position shown in Figure 13, window 262 allows to arrive optical sensor 258 from the light of light source 256.Optical sensor 258 senses described light and provides signal to processor 212, and this Signal aspects spring-biased switch 200 resets.
This embodiment can two kinds of different startup (firing) pattern operations, and it is that user is selectable by mode selection switch (not shown).Under sequential operation mode, based on switch or sensor, the press-in of WCE184 produces WCE signal.Correspondingly, processor 212 execution of program instructions, makes the energy content of battery be provided to motor 114.Processor 212 also can make sensor 216 be energized based on WCE signal.When the kinetic energy that flywheel speed sensor 220 shows desired quantity has been stored in flywheel 130, processor 212 has controlled motor 114 to keep the velocity of rotation of the flywheel 130 corresponding to desirable kinetic energy.
If needed, operator can be warned the situation that can utilize kinetic energy.As an example, when the velocity of rotation of flywheel 130 is lower than ideal velocity, processor 212 can make red light (not shown) be energized, and when the velocity of rotation of flywheel 130 is equal to or greater than ideal velocity, processor 212 can make green light (not shown) be energized.
Except making energy be provided to except motor 114 when WCE184 depresses, when battery power is applied to motor 114, processor 212 starts timer.If flop signal do not detected before expiration of the timer, battery power will remove from motor 114 and order must restart.Timer 2 22 can be used to provide timing signal.Interchangeable, independent timer can be provided.
But if trigger 196 is handled, processor 212 receives the flop signal from trigger switch or trigger sensor 216.Then processor 212 makes to the energy supply discontinuity of motor 114, as long as the kinetic energy in flywheel 130 is enough, allows motor 114 freely to be rotated by the energy be stored in rotary flywheel 130.Processor 212 starts first timer 222 further and controls solenoid 124 under "on" position.In response to from first in the signal of drive block sensor 178 or the termination of timer 2 22, processor 212 follow procedure interrupts to the power supply of solenoid 124.WCE switches/sensors and trigger switch or trigger sensor 216 all again must reset before another has circulated.
Interchangeable, operator can select bump (bump) operator scheme by using forestland selector switch.In conjunction with in the embodiment of trigger sensor, selector switch is positioned at during bump pattern is arranged and trigger sensor is energized.In this mode of operation, processor 212 will provide battery power in response to WCE switches/sensors signal or trigger switch/sensor signal to motor 114.When receiving residue input signal, processor 212 confirms that desirable kinetic energy storage is in flywheel 130, then makes interrupt to the power supply of motor 114 and provide battery power to solenoid 124.In response to from first in the signal of drive block (driver block) sensor 178 or the termination of timer 2 22, processor 212 follow procedure interrupts to the power supply of solenoid 124.
Under bump operator scheme, two input in only one must again reset.When another input resets again, as long as at least one input keeps state of activation, after solenoidal power supply removes and then, processor 212 will provide battery power to motor 114 at once.When the input again resetted provides signal to processor 212 again, said sequence starts again.
An alternative solenoid component as shown in figure 15.Solenoid component 280 can be used in substantially identical with securing member percussion device 100 securing member percussion device.Solenoid component 280 comprises the solenoid 282 by pin 284 orientation, and this pin moves along axis, and this axis is parallel to the tongue piece 286 of lever arm unit (not shown) in a way, and it is configured to similar lever arm unit 126.Pin 284 is connected to knee shape hinge 290 by axle 292 and pin 294.Knee shape hinge 290 is comprised and is pivotally connected to the upper arm 296 of tongue piece 286 by pin 298 and is pivotally connected to the underarm 300 of frame part 302 by pin 304.Block 306 is positioned on underarm 300.
The operation with the securing member percussion device of solenoid component 280 is basic the same with the operation of securing member percussion device 100.Main difference is that, when solenoid 282 is controlled under power on condition, pin 284 is drawn in solenoid 282, therefore makes the side of axle 292 arrow 308 shown in Figure 15 move up.Axle 292 is along tractive knee shape hinge 290 on the direction of arrow 308.
Because the upper arm 296 of knee shape hinge 290 is pivotably connected to tongue piece 286 by pin 298, and the underarm 300 of knee shape hinge 290 is pivotably connected to frame part 302 by pin 304, and knee shape hinge 290 is pushed to elongation state.In other words, upper arm 296 in the counterclockwise direction around pin 298 pivotable underarm 300 in the clockwise direction around pin 304 pivotable.The extension of knee shape hinge 290 makes lever arm unit 288 pivot in the mode similar to the rotation of lever arm unit 126.
Another replaceable solenoid mechanism as shown in figure 16.Solenoid mechanism 310 comprises the solenoid 312 with solenoid pin 314.Solenoid pin 314 is operably connected to the slide plate 316 be positioned on slide block (slide) 318.Arm 320 is at one end pivotably connected to slide plate 316 and is connected to lever arm 322 at the other end.
Solenoid mechanism 310 operates in securing member percussion device in the mode identical with solenoid mechanism 280 substantially.Its main not being both instead of knee shape hinge, and as knee shape hinge 290, solenoid mechanism 310 comprises slide plate 316.Therefore, solenoid 312 energising makes slide plate 316 move through slide block 318, therefore promotes lever arm 322 and rotates.In a further embodiment, equip wheel 332 by giving slide plate 330 and reduce frictional force, as shown in figure 17.
